ادكر الخاصية الفيزيائية التى تتغير مع درجة الحرارة في الترمومتر السائلي العادي

The content discusses the physical property of temperature change in a regular thermometer. It mentions that the regular thermometer contains a substance called mercury, which expands when exposed to heat. Scientists have discovered that mercury has a higher coefficient of thermal expansion compared to other substances. This allows the regular thermometer to accurately measure changes in temperature based on the expansion of the mercury.
